I have a dedicated server which I am managing myself. I have experienced a strange thing today. The whole Apache daemon seemed to be hung. Every Web request resulted in a timeout, even when executed from localhost. The CPU usage has been minimal (like 99.7% idle). No MySQL long statements being executed, nothing. mod_status did not help me, because requesting the status also hung (as it is retrieved by HTTP). After Apache restart everything went back to normal.
I have no idea what could have happened, and moreover Apache does not provide me with any tools to diagnose it (because mod_status doesnot work in such situation). So I am asking you for help - do you have any idea what I could do when such problem repeats to diagnose its source?
We have flash files site hosted on dedicated server in that Apache is utilizing the more CPU. When the server reached more than 1000 connections server get down automatically.
I moved my sites to new linux server of mine (apache, mysql, php).
From that time i experienced some bigger websites hanging for like 2-3 seconds before they start loading. I mean when im browsing thru my website i click link, submit something and it waits saying in status field like "Waiting for mywebsite.com"
So i want to ask what apache, php etc values, what to check on server?
NOTE: my server is NOT overloaded (I am checking "top -c" stats) so don't suggest me to upgrade etc.
I have impression that it is waited until website elements are loaded and then webpage load very quickly after mentioned 2-3 seconds delay..
I have a problem. When MSN Search robot looks through my VPS, the machine is going "asleep", e.g. Apache2 (Port 80) doesn't answer at all. Here is the last falling:
Code: 23:14:15 up 4 days, 9:06, 5 users, load average: 37.18, 31.25, 27.46 I hardly ever can enter 'pkill apache2' to kill Apache2 processes. Here is my Apache2 configuration (timeouts, prefork, e.g.):
Code: Timeout 30 KeepAlive On MaxKeepAliveRequests 20 KeepAliveTimeout 5
I seem to be having troubles getting yum to run. The problem occurs when I try to run yum via ssh using putty or install perl modules through whm.
When I try to run it, I generally get: Loading "fastestmirror" plugin And nothing after that, even if I wait a while. This happens when I run: yum update yum install imagemagick (my current reason for trying to get yum to run) yum clean all (probably other yum commands) If I run yum with --noplugins, it just skips putting out the fastestmirror message. Some info on my system: CENTOS Enterprise 5.2 Kernel Version: 2.6.18-92.el5 Intel C2D e6750 WHM 11.23.2 cPanel 11.23.6-R27698
We have recently launched a new website with a SSL homepage which houses our login. Our website moved to a new IP address, therefor we moved the certificate to the new server as well. Thus far, we have had NO problems with the site with the exception of 2 MAC users who's browser hangs when they try to navigate to the site now. They can access other HTTPS sites, and they can access pages on OUR site that are NOT HTTPS, but when trying to browse to our HTTPS Page, the browser hangs. This is not just ONE browser on their MAC, it's EVERY broswer on their machine (Firefox, IE, Safari). It connects, but then doesn't load anything onto the screen. We tried clearing their DNS cache on their machines with no avail. To this point, we are stumped. We have identical machines, with idential OS and browser versions and everything tests fine. It is obviously something on their machine, but we don't know what it is. We have run out of ideas. Any MAC users that can lend a hand here? Is there a way to delete the certificate on the MAC and have it redownload to the user?
problem I was having which was Windows Small Business Server 2003 would hang on boot up. I never got the time to reinstall the server until now.
I have installed the server and applied all updates. This worked fine until I install the Windows Server 2003 Service Pack 1 or 2. When I install SP1 or SP2 on reboot the server loads the Dell splash screen then the monitor LED light goes orange then green then orange and then just hangs with a blank screen.
I can boot into Safe Mode and uninstall the Service Pack and I can then reboot without any problems. I have installed ADAM SP1.
I am running into a problem with my home linux server running Fedora 8 (2.6.26.6-49.fc8). The problem is with my SSH sessions, in that they hang or freeze when I try to run certain commands such as (ps -auxt or top) or when trying to edit (/etc/httpd/conf/httpd.conf) via VI or Pico. I am able to edit my pure-ftpd.conf file with little to no trouble through either Vi or Pico however. I did some research already on openssh.org but my problem does not resemble the tcp timeout issues I've seen described. When the SSH session hangs I'm forced to disconnect and then reconnect. Just curious if anyone has any ideas as to what I can try to resolve this problem.
I just got a new server and discoverd very strange problem. It happends 2-3 times every hour. When I try to access some webpage which connects to MySQL, I get page header and then page hangs for some 1 minute. After some 1 minute everything is back to normal. I can open several windows with different websites hosted on my server and the same problem is in all windows. At the same time I can access al websites without MySQL connections.
I have a dedicated machine collocated at some hosting provider and after a while (14 days or so, but timeframe is not constant) it hangs for no apparent reason. It happened 2 times already. Nothing in the logs (it logs everything), nothing at all.
Before the commission the machine was running for a month without any problems.
The first time it happened the tech guy plugged in monitor and keyboard and could not see anything on the display. Before that machine was not loaded with any traffic, nobody should have actually known it is there (except for some DNS traffic). It took some 20 days of uptime.
The second time it happened was yesterday, after some 15 days of uptime.
I suspect hardware malfunction because I have 2 "identical" (OS & progs, not the hardware) systems running without any problems. It is an HP DL380 G5 machine, the problematic one.
This happens when I try to add a new domain or when I am trying to remove a domain. It just hangs, the browser says waiting on server while plesk just hangs. This is a fresh new install of Plesk 12 as well. I added a bunch of new domains tonight. No crazy changes or anything to plesk. I have found nothing so far in my search.
I'd like to upgrade my server from Ubuntu 12.04 to Ubuntu 14.04. The idea is to migrate my actual server (S1) to another one (S2). Then, format and install ubuntu 14.04 with Plesk on S1, and finally migrate the data from S2 to S1. Is it a good solution? Is it possible to do this using only one server? I don't know if I can do it making a backup, install Ubuntu 14.04 and then, restore the data into the server.
However, I have a problem with the migration agent. When I go the migration page, the migration agent tries to update itself and it keep at 0% forever (I attach an screenshot).
I have an issue with my daily backup. I configured to have a daily backup on an external FTP server. Everything looks to work correctly but in the panel I see that the task is a 100% forever. Never finishing completely.. So the next day, the task is not starting.. I have to remove manually the task in backup manager screen.
here is the last lines of the log file (in /var/log/plesk/PMM/backup-2015-01-20-20-46-02-824)
On our production service, we've been getting numerous malformed POST requests to some of our CGI scripts that are showing up as 500 errors in our logs. They are malformed in the sense that the actual content length doesn't match the Content-Length specified in the request.
Here's the most trivial example I can come up with that reproduces the problem for us:
In addition to the 500 error in the access log, we see the corresponding error in the error log:
(70014)End of file found: Error reading request entity data
Based on the nature of the POST request and the error response, it does appear that Apache is doing the right thing here.
The POST never actually makes it as far as the script being targeted (/some_valid_alias in the above example); in other words, Apache returns 500 to the client, writes the error to the error log and never executes the script.
Is there a way to capture/avoid internal Apache errors like 70014, and return some other HTTP status besides 500 (like 403)? It's particularly annoying in our case, because our server sends us an email for all 500 errors.
So far, our best "defense" against these 500 errors is to disallow POST for these aliases, which normally just ignore the POST data anyway (when the request is not malformed):
I've had this problem a long time now with my hosting network and decided to ask here hoping I get some good solutions, or if someone is willing to looking at this (I'll pay if they want).
Here's what I mean: [url]
Problem is as you can see apache processes constantly rise infinitely, at least until I restart apache (/etc/init.d/httpd restart). The point of restart is shown in red lines.
And after restart, it goes down again for X amount of hours then eventually rises again infinitely until it's restarted again.
But the fact that after restart it remains down, it means it had the potential to be down all along.
So my question is: what could be causing this and does anyone have solution to keep them low at all times (as per graphs)?
The Linux Server got down when the MaxClients 256 is reached. Error Log:
"server reached MaxClients setting, consider raising the MaxClients setting"
So that I have tried to increased the MaxClients Value to 500, after changed the value in httpd.conf and restart I get following error message.
" [notice] SIGHUP received. Attempting to restart WARNING: MaxClients of 500 exceeds ServerLimit value of 256 servers, lowering MaxClients to 256. To increase, please see the ServerLimit directive."
So that I tried changed the Server limit in /usr/local/apache/include/httpd.h header file. but it seems like there is no entry.
Apache Version : 2.2.8
So I have added the ServerLimit 500 entry in httpd.conf file and restart the httpd service. But still shows the same warning mesg. Please help me regarding this.
We have the Dedicated server for Flash Game Server with following configuration.
RHEL4 OS 2GB RAM Intel(R) Xeon(R) X3210 @ 2.13GHz Cpanel Installed. Apache 2.2.8 PHP 5.2.4 MySQL 4.1.2 (MySQL Server is working in differend server)
This redirect works fine on Apache 2.2.8, but doesn't work on Apache 1.3.41
The following is the entry from error_log: RewriteRule: cannot compile regular expression '^sap-latest-news/([0-9]*)/([A-Za-z0-9_-.]*).htm$'
A simple Rewrite is working fine in Apache 1.3, but the above regualar expression doesn't seem to be working on Apache 1.3. Does anyone know whether Apache 1.3 doesn't support it?
I am having an issue where I have a server that Directadmin is installed on. I go to the a url that is on the server and all i see is the default page of apache saying congrats, it is installed. Although there is no file like that in the public_html any longer and I can see my files in the public_html folder of that specific site.
I'm building a new server for a predominantly php5/mysql5 website and was wondering which version of apache to put on. I know there are some issues with PHP and Apache in MPM, but what's the performance comparison between Apache 1.3 and Apache 2 Prefork?
I am trying to install dedicated web server on my Slackware 12.0.0 machine. I am a novice in Linux, but succeeded in MySQL & proFTPd installation. The problem now in httpd compiling.
I downloaded the latest Apache 2.2.9, but it needs Apache Portable Runtime 1.3.2 installed. I downloaded 1.3.2 version and run ./configure

if you were to be presented with a choice to run Apache 1 or Apache 2 given you'd have more or less the same support requests etc, and the same underlying user requirements to implement either one or the other, which one would you choose and why?
I noticed that Hsphere Parallels control panel 3.2 release as may well other control panels, offers such possibility. Personally I've been educated from senior members of previous organizations to appreciate Apache 1 as the defacto version of the web hosting industry (choice here being apache 1 and 2, not IIS or any other web servers) Could you kindly simply attempt to enlighten me given, indeed support for both will/might remain the same in the future?
